Thanks Jim, but the virus generally doesn't go around individually but within drops of moisture which are much larger. Apparently masks used properly (eg by healthcare professionals) reduce infection rates of the wearer by 80%...Apparently, if you were to scale everything up so that this virus were the size of a coin, the holes between the fibres in cloth masks like these would be eight feet in diameter. Make of that what you will...

Hi,There's been a lot of research done on the wearing of masks and several conclusions drawn.
One paper I read tested what happens when people with a virus sneeze while wearing a mask. They found traces of the virus on the outside of the mask but not inside. That particular report went on to say that although there was traces of the virus on the outside of the mask the distance the virus traveled was significantly reduced.
You can also get those little bendy strips that go over the nose part of a mask to make it fit better, online. Or apparently you can make them by cutting the soft metal base of nightlight candles.For those who are interested bfe99 meltblown filter fabric (for disposable Medical grade filter liners) is available on both Amazon and Ebay.
the GOV.UK website is now distinguishing between ‘face masks’ (reserved for clinical settings and healthcare professionals) and ‘face coverings’ ( anything from a bandana to a scarf to a homemade sock mask) for members of the UK public who are in enclosed spaces (shops, offices, etc) where social distancing is difficult.

I have noticed on TV that many doctors and nurses wear a surgical mask on top of their FP3 mask. Does anyone know why?I wear mine on the back of my head in case the virus tries to sneak up on me.
I imagine it is because they can throw away the cheap surgical mask and any virus that may have landed on it rather than a FP3 mask that is in short supply.I have noticed on TV that many doctors and nurses wear a surgical mask on top of their FP3 mask. Does anyone know why?
I think I have heard the phrase 'like stopping a mosquito with a chain link fence' but at least we will make everyone feel better.Apparently, if you were to scale everything up so that this virus were the size of a coin, the holes between the fibres in cloth masks like these would be eight feet in diameter.

You should see my previous post as to why that analogy isn't accurate. That exact phrase is quoted...I think I have heard the phrase 'like stopping a mosquito with a chain link fence' but at least we will make everyone feel better.
Hi,
Interesting paper come out in the States by 200 scientists on the airborne passage of covid. It encourages the use of facemasks in all indoor situations.
